| |
See commit message for rust binder commit for details.
Signed-off-by: Alice Ryhl <aliceryhl@google.com> --- Changes in v6: - Fix rebase mixups. - Include benchmark in commit message. - Link to v5: https://lore.kernel.org/r/20251112-binder-bitmap-v5-0-8b9d7c7eca82@google.com
Changes in v5: - Rename NO_ALLOC_MAX_LEN to MAX_INLINE_LEN. - Update all uses of MAX_LEN/MAX_INLINE_LEN to reference the new constants. - Link to v4: https://lore.kernel.org/r/20251110-binder-bitmap-v4-0-5ed8a7fab1b9@google.com
Changes in v4: - Keep existing IdPool constructor (renamed to with_capacity). - Undo docs changes that were due to the removal of the existing IdPool constructor. - List id < pool.map.len() as invariant for UnusedId and mention it in as_u32() comment. - Fix [`acquire`] docs links. - Link to v3: https://lore.kernel.org/r/20251028-binder-bitmap-v3-0-32822d4b3207@google.com
Changes in v3: - Also update documentation to fix compile errors. - Use new_inline() instead of new_small(). - Reword commit message of "rust: id_pool: do not supply starting capacity" - Change UnusedId::acquire() to return usize. - Link to v2: https://lore.kernel.org/r/20251021-binder-bitmap-v2-0-e652d172c62b@google.com
Changes in v2: - Use id_pool. - Link to v1: https://lore.kernel.org/r/20251020-binder-bitmap-v1-0-879bec9cddc1@google.com
--- Alice Ryhl (6): rust: bitmap: add MAX_LEN and MAX_INLINE_LEN constants rust: bitmap: add BitmapVec::new_inline() rust: id_pool: rename IdPool::new() to with_capacity() rust: id_pool: do not supply starting capacity rust: id_pool: do not immediately acquire new ids rust_binder: use bitmap for allocation of handles
